JACK DON, OF DETROIT, MICHIGAN.

DRINKING-GUI.

To all wlmm it may concern:

Be it known that I, JACK DON, a sub'ect of the Emperor of Japan, residin at etroit, county of Wayne, State of ichi an, have invented a certain new and useful provement in Drinking-Cups, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to 'make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to sanitary vessels and an object of my improvements is to provide a vessel having a definite and fixed area of contents which maybe constructed by folding integral sheets of material, such as paper, and which, when so constructed shall have its walls continuous and not liable to leak. Incidentally a handle is provided for the vessel.

I secure this object in the device illus-' trated in the accompanying drawings, in which,-

Figure 1 is a perspective view showing the complete vessel in its operative form.

Fig. 2 is an elevation looking from the right and above Fig. 1.

Fig. 3 is a diagrammatic view of the sheet of material from which the vessel is constructed, the lines upon which the sheet is folded being indicated by broken lines.

Fig. 4 is a plan view of the sheet shown in Fig. 3 after the performance of the first step toward constructing the vessel therefrom.

Fig. 5 is anelevation looking from the left of Fig. 4.

Fig. 6 is a side elevation of Fig. 4.

Fig. 7 is an elevation similar to Fig. 6 after the second operation of folding the sheet has been performed.

Fig. 8 is a view similar to. Fig. 7 after the third operation has been performed.

Fig. 9 is a plan view illustrating the second operation.

Fig. 10 is a plan view illustrating the third operation.

Fig. 11 is a side elevation similar to Fig. 2, but illustrating the fourth operation of constructing the vessel.

Fig. 12 is a section on the line XII-XII, .Fi' 11, to an enlarged scale.

ig. 13 is a plan view indicating the fifth and final operation in the construction of the vessel.

Specification of Letters Patent. Patented Feb, 22, 1921, Application filed November 7, 1919. Serial No. 336,266:

FFigi314 is a section on the line XIV-XIV,

ig. 15 is a side elevation of the completed vessel. Fig. 16 is a perspective view of the secur- 111% clip.

ig. 17 is a transverse vertical section of the vessel. to an enlarged scale.

It will be observed that in Fig. 1 there is a completed cup rectangular in cross-section and is provided with 'a handle extending from the center of one of its sides. The square cup is made up of a bottom panel a, what may be called end panels 6 and 0 and side panels 03 and 6. This cup is formed by properly folding an integral sheet which may be made of impervious paper. Referring to Fig. 3, the first operation of folding is to bend up the end panel b about the line a and at the same time bending up the side panels d and e about the lines aand a the paper at the same time bending outward on the lines m and p and inward on the lines 01 and e which latter comes into position adjacent to the line b and 6 When the side panels 01 and e are bent upward the panel 1 s o w and the panel t u w y are also bent upward at the lines a and 0 respectively, which are continuations of the lines a and a This completes the first operation in the folding of the sheet and the sheet now-presents the appearance shown in Figs. 4 and 5 in which flaps f and 2' extend upward above the upper edges of the triangular. pieces n and 12, these flaps being extensions, respectively, of the triangular parts m and g.

In the second operation the panel 0 is turned upward into a plane parallel tothat of b, the paper bending on the lines 0 c and r in the latter panel being an outward bend. The parts in this position are shown in plan in. Fig. 9 and in elevation in Fig. 7.

In the third operation the laterally extending, substantially triangular wings shown in Figs. 4 and 5 are folded against the panels d and e, as illustrated in Fig. 10. This brings the flaps f and 71 against the flaps g and For the fourth operation the flaps g and j carrying with them respectively the flaps h H and k K are turned outward, the flaps f and 2' also bending outward by the flaps g and folding above and outside of the flaps an z.

Inthe fifth and last operation, the panels 1 8 aw and t u w 3 which have been folded into triangular shape. in the lines 1) and w are bent inward toward each other at the same time bending each ofthese flaps outward on the line The two lines 1' come together at the center of the panelc and the I outwardly turned portions come-to ether Y 1. The method of for'min forming Yhehandle of the cup. The c ip 16 is now p aced withithe portion 16 against the inner'surface of the panel c,'the handle of the cup coming within the notch 16" andthe finger 16 extending'over the inwardly folded flaps H andK. Thus the vessel is formed and 'is held firmly in shape having a considerable and permanent contents area.

Claims "position, the other pair of flaps thus formed ing turned toward each other in part against the side of the vesseland in part at right angles thereto to form a handle.

2. The method of forming a vessel c'onsist' in bendin "a rectangular sheet of material so as to orm a rectangular bottom and four rectangular sides, each of said sides having an edge in, common .with anedge of I said bottom, each of the rectangular parts a vessel conof said sheet between said sides being folded upon itself at a diagonal thereof, the bend being outward, the constituent flaps of one pair of flaps thus formed being turned against the rectangular sides of the vessel in opposite directions and secured in this pgsition, the other pair of flaps thus formed ing turned toward each other in part against the side of the-vessel and in part at right angles thereto to form a handle, a part 0 the material of approximately rectangu lar shape having been turned over the last named pair, of flaps before the same was bent to formthe handle.

3. The method of forming a vessel consisting in bending terial so as to and four rectangular sides, each of said sides a rectangular sheet of maorm a rectangular bottomhaving an edge in common with an edge of said bottom, each of the rectangular parts of said sheet between said sides beingfolded.

upon itself at a diagonal thereof, the bend being outward, the constituent flaps of one pair of flaps thus formed being turned against the rectangular sides of the vessel in opposite directions and secured in this position, the other pair of flaps thus formed being turned toward each other in part against the side of the Vessel and in part at right angles thereto to form a handle, passing a 'clip over the side of the Vessel adjacent to the arm and causing the outerportion of said .clip to engage the side of the handle for the purpose described.

In testimony whereof, I sign this specification. Y

JACK non.
